prostoalex writes "Japan's major telecom provider NTT DoCoMo plans to use fuel cells for its 3G phones. 'Users of cellphones with a fuel-cell battery would carry a cigarette lighter-type fuel container to refuel the battery', says Reuters."

prostoalex writes "While the Simplex algorithm is considered to be one of the most widely used algorithms in complex networks, the reason for its efficiency has been so far not too clear. Daniel Spielman and Shanghua Teng discovered the secret of why the Simplex algorithm works so well by introducing imprecision into the worst-case scenario analysis. Their article will be published in Journal of ACM, although MIT Technology Review at the aforementioned link quotes Spielman expressing his doubts whether anyone will be able to make it through 80-page document filled with equations and formal explanations of the method."

prostoalex writes "How many times have you met an interesting person, who happened to check out the same book in the library, or listen to the same music as you do? Researchers from University of Chicago suggest that it would be kinda cool if you could find like-minded people by analyzing the queries submitted to a Web search engine. Their PDF paper explains the research in more detail."

prostoalex writes "May issue of MIT Technology Review discussed the implications of a globalized patent system. For small inventors, it argues, the cost of globalizing the rights for their invention are just unbearable. For example, in Europe it costs about $7,000 per country to file a patent application. As an article bonus, some people might like to take a look at the list of the largest patent holders per industry in PDF format."

prostoalex writes "The Unix-Haters Handbook, publication year 1994, is now available online for free as a single PDF file. Apparently some suburban Seattle company has agreed to host this 3.5MB file on its servers. The anti-foreword is written by no other but Dennis Ritchie, who proclaims: 'Here is my metaphor: your book is a pudding stuffed with apposite observations, many well-conceived. Like excrement, it contains enough undigested nuggets of nutrition to sustain life for some. But it is not a tasty pie: it reeks too much of contempt and of envy.'" This is what should happen to more out-of-print books.

Alex Moskalyuk writes "Ben Hammersley's Content Syndication with RSS is a step-by-step guide to implementing RSS. This standard is gaining popularity among the Web community, and some of your favorite sites might syndicate their content as RSS feeds. The new O'Reilly publication focuses on many aspects of this standard, and is of primary interest to developers, Web site designers, data architects and anyone interested in distributing their data around the Web." So if you have a steady stream of information for your customers, family, or fans, read on for the rest of Alex's review. Content Syndication With RSS author Ben Hammersley pages 222 publisher O'Reilly rating 8/10 reviewer Alex Moskalyuk ISBN 0596003838 summary Introduction and guide for RSS implementations

The first three chapters are primarily discussing the multiplicity of RSS standards. While with some other technologies it might seem a bit excessive, remember that RSS is a forked project with the forks at this moment bearing little resemblance to one another. The abbreviations even have different abbreviations - RSS means Really Simple Syndication if you are using RSS 0.91 or RSS 0.92, that was developed by Dave Winer. RSS means RDF Site Summary if the version you're using RSS 1.0. The development credits in this case go to RSS DEV team. To confuse you even more, the RSS 2.0 standard is deciphered as... correct, Really Simple Syndication again.

Hence chapter 4 discusses Winer's implementation (simplistic and user-friendly), while chapter 6 focuses on RSS 1.0 (RDF-compliant and data-architect-friendly), and chapter 8 talks about RSS 2.0 (improved RSS 0.9x). Chapter 4 is available online as a PDF file. Section 4.4 is recommended for those interested in promoting their RSS feeds as it provides pretty good reference to meta data.

Chapter 9 is perhaps of special interest to Web developers and administrators out there. It presents several code samples to properly parse RSS and present the result in readable HTML. The examples include (a) parsing with XML::Simple in Perl, (b) parsing with Perl regular expressions, (c) parsing with XML::Simple and sending the headlines to cell phones via WWW::SMS, (d) parsing via XSLT transformation. Python, PHP and ASP folks might feel left out due to the abundance of Perl examples, but if you got so far in the book, you can probably apply the regular expressions example or search for appropriate support for RSS format in your preferred language.

Going beyond the standard itself, RSS directories, aggregators and readers are discussed. Author makes a distinction between the last two by classifying Meerkat-like services into aggregators and desktop or Web applications designed to present the information to the user into readers. The chapter also provides information about Syndic8, its API, and describes the feed registration process. OReilly's Meerkat is also discussed in chapter, together with reference table for its API (you can make Meerkat generate HTML or RSS news headlines on certain topic or using certain keywords by providing a right query to its Web interface).

The book is quite a smooth read for a text describing the details of data specification. The chapters are informative and the book is not overloaded with useless information just to increase the page count. The tips are quite useful for someone, who is knew to the field and answers some questions not covered by standards (e.g., how often should you request an RSS feed, what to do if you're being screen-scraped, etc.)

I like the way the author divided the chapters into RSS 0.9x/2.0 and RSS 1.0 and kept two worlds apart. Most of the time you probably won't be interested in developing a feed to support both standards, but would like to focus just on one. The examples in Perl are perfect with me, although for someone new to Perl or programming in general those examples with abundant regular expressions might look a bit convoluted. Kudos to the author for not expanding on the topic, like many do, and providing an example of a script for RSS manipulation in every possible language out there.

What's missing? I wish more pages were dedicated to desktop RSS readers. FeedReader, HotSheet, Syndirella, Beaver and SharpReader are excellent end user applications currently gaining some popularity among those who'd prefer to browse the favorite headlines at a glance, instead of going to a dozen of sites every morning. To be fair, there's a huge list of readers in Appendix, and some applications mentioned above only came around in the last few months, which was probably after the book hit the press. Some sites also didn't make it into the book. I like DailyRotation and FreshNews that borrow from Meerkat's versatility and provide their own feed portal.

Overall, the book is a pretty good developer's guide to RSS standard. Accompanied with helpful illustrations and numerous tips it's an excellent resource for those unfamiliar with RSS and a helpful reference for those who have been doing Web syndication for a while.

prostoalex writes "John Markoff and G. Pascal Zachary from The New York Times take a look at Google, its already dominant position in the field of Web search and its increasing influence in the field of Internet advertising. Google is driving advertisers away from larger advertising venues, like AOL-TW et al., since (surprise!) people actually pay attention to relevant text links and are quite annoyed by pop-ups and similar "innovations". Some interesting data about Google: number of employees is about 800, number of buildings is 4, number of servers is 54K, for which there are about 100K microprocessors and 261K hard drives. This is claimed to be the largest computing system in the world, and that also raises barriers for anyone entering the field of Web search - most of companies out there can only imagine a Beowulf cluster of these, let alone build them so that the Web searches are delivered within a second."

prostoalex writes "The Big Blue will bundle J2EE-based word processor, spreadsheet, and presentation graphics applications in its WebSphere portal. What's more interesting is that the package is server-side, with functionality of the application being delivered to the user over the network. Both CRN (linked above) and The Register considered that a major move against MSFT."

Slashback is packed tonight with updates and clarifications on several fronts: read on below for, among other things, BitTorrent download stats after the recent Red Hat 9 release, the BSA's questionable statistical methods when it comes to calculating incentives and losses in the source-secret software world, and (can you believe?) yet another way to assemble an eerie pulsing light fixture.

Click on through for some impressive graphs ... . bramcohen writes "Since RedHat 9 got /.'ed last week there have been over ten thousand complete downloads using BitTorrent. Initial traffic got very high, transferring over a gibibit a second. All throughout the BitTorrent servers, run by volunteers using stock tools, held up just fine. Meanwhile downloads from RedHat Network, only available to subscribers, transferred at a crawl. The third Animatrix also got quite a few downloads. Thanks to everyone who left their downloaders running, and David Stutz and Eike Frost for setting things up."

If you exaggerate enough the first time, subsequent revisions sound like concessions. Russell McOrmond writes "An article in ITBusiness.ca includes references to the methodology of the BSA studies, and how it confuses Free/Libre and Open Source Software with piracy. There are some related articles talking about CAAST/BSA on my work weblog from the past."

Tap, Tap, Tap. feagle814 writes "Recently, I saw a question on Ask Slashdot that intrigued me. The person was asking for ideas relating to building your own glowing and color-changing ball. Being the kind of person to take such a general request for comments and turn it into a personal reason for living, I quickly skimmed the description on ThinkGeek and came up with these requirements for my project:

1. It must meet the generic description of the Ambient Orb,
2. It must cost less than $50 to make,
3. It must be wireless, with at least a 30-foot range, and
4. It must be controllable by home computer.

After much deliberation, I came up with the following solution. I've included pictures and instructions, as well as a recounting of my experiences."

Not just a simulation. Olmy's Jart writes "This is a followup to yesterday's article on "Samba Exploit Discovered, Fixed". Digital Defense has posted an apology to the Samba Team for posting a complete live working exploit (not even a mere "proof of concept", but a zero day rooter) on their site for this vulnerability. The exploit has been taken down, for what that's worth now. This is being reported in an article on ZDNet AU. Digital Defense now claims that this was done without the approval of their management."

Funny, CompUSA is finally selling duplicators, too. Unominous Coward writes "According to this article, the man who planned to install CD copying machines around Australia has withdrawn from the idea. Not surprisingly, this was after a lawsuit by the music industry."

Anyone who would like to buy me one is free to do so. prostoalex writes "Sharp Zaurus deal is back at Home Shopping Network. Sharp Zaurus SL-5500 is $199, but a coupon code HSN4897 knocks the price down by 15%. With standard shipping the order comes to around $173."

We need both more Korean food and more Korean electronics. Jo "directhex" Shields writes "HEXUS.net has completed its extensive messing around with GamePark's GP32 Handheld, which recieved a mention a couple of days ago on Slashdot (and recieved the usual thrashing from members too busy to read the article but not too busy to post trashy ill-informed comments about it).

It should help to clear up a few myths about what the unit is, what it tries to do, and what it succeeds at doing. Read the review, and pass mighty Slashdot Judgement."

prostoalex writes "Researchers have developed a fuel cell that can be recharged with few milliliters of alcohol. MIT's Tech Review quotes the researchers claiming that those 'cells could eventually be used as a replacement for any rechargeable power source, including laptop and PDA batteries'. I suppose the scientists still have to explain all those bills from liquour store that say 'research material' on them."

prostoalex writes "AMD and Fujitsu will form a new memory company. While corporations typically form new spinoffs every time you turn around, this one is different, claims ZDNet, since it looks like AMD will be splitting into two companies, one dealing in the microprocessor market, another in memory."

prostoalex writes "Researchers from Humboldt University found a way to build self-assembling networks. By emulating the behavior of ants and insects the team, which is led by Frank Schweitzer, demonstrated a simulation where agent-based architecture was able to quickly assemble itself into a network and quickly react to a broken link or damages. Schweitzer's research papers are available off his personal Web site. The scientific paper referred in the original article, Self-Assembling of Networks in an Agent-Based Model is available off Cornell server."

prostoalex writes "The Industrial Physicist sums up the recent advances and developments in the world of computer vision. They mention an application for human-computer interfacing using a Webcam, Philips Research Lab Seeing with Sound product, which augments vision for visually impaired, as well as various frontal face detection applications."

prostoalex writes "Caltech computer scientists announced the protocol, capable of delivering 8,609 Mbps over the Internet, using 10 simultaneous flows of data. The research project was conducted in partnership with CERN, DataTAG, StarLight, Cisco, and Level 3. The practical applications, according to the press release, is ability 'to download a full-length DVD movie in less than five seconds'. There is a number of papers and scientific publications available."

prostoalex writes "IDC has a new report out, claiming that revenues for LCDs by the end of this year will top the CRT revenues. The only market not susceptible to the shift will be gaming and graphics-intensive applications, where the refresh rates of LCDs are not satisfactory yet."

prostoalex writes "The new issue of Intel Technology Journal has a lengthy article on a new platform, developed in Intel labs. The Open Runtime Platform: A Flexible High-Performance Managed Runtime Environment describes the platform that is capable of running both Java VM and Microsoft's CLI, on both Windows and Linux platforms. Full PDF version is also available."

prostoalex writes "Internet's largest retailer is setting up a domain name registration business. Wall Street Journal recently found out that in December Amazon.com got approved as domain name registrar. According to people from ICANN, the registration included rights for .com, .net,. org, .biz and .info TLDs."

prostoalex writes "Wired News unveils the secrecy behind Overpeer, the company whose mission is to infiltrate peer-to-peer networks with low-quality audio and video files, or corrupted chunks of data which carry the same name and have the same size as originals. Apparently OverPeer even managed to procure a USPTO patent on (a) producing an advertising digital music file by deteriorating or damaging a sound quality of an original music file of a record of a cooperating record corporation; and (b) distributing the advertising digital music file through the communication network."

prostoalex writes "Washington Post talks about recent innovations in the world of windows (yes, lowercase). A Minnesota company is offering windows that double as entertainment centers, being used as projection screens for home entertainment systems and DVD players. A Yale professor is quoted to be excited about new product: 'One minute you're looking out your bay window at your neighbor's back yard, and the next you're watching Tom Cruise and 'Top Gun''."

Alex Moskalyuk writes "Philip J. Kaplan's F'd Companies is a compilation of famous and not so well-publicized dot-com flameouts. Most of the companies that are described in the book do not exist today, for some others the domain names are being used for similar businesses, but the original management and business plans are gone. Even though F'd Companies presents several chapters in the table of contents, it's better viewed just as compilation of dot-com mishaps, with about one or two pages dedicated to each company." Read on for more Schadenfreude. F'd Companies author Philip J. Kaplan pages 224 publisher Simon & Schuster rating 8/10 reviewer Alex Moskalyuk ISBN 0743228626 summary Spectacular dot-com flameouts

Everyone who's visited the author's Web site at least once has probably noticed Kaplan's style of writing -- raunchy humor abundantly supplemented with free use of four-letter words, which is then mingled with frequent references to the author's male organ and Internet pr0n industry. Not that the book loses its charm because of it -- F'd Companies would probably make a poor choice for a kid's present, but after getting used to Kaplan's style of writing the obscenities and euphemisms add hilarity to otherwise dry management text. Here's Kaplan's contemplation on the value of domain name Wapit.com (now defunct):

The company had a cool name though. I love to wapit in the morning when I first wake up with my stiffy, wapit in the stall of the men's bathroom at lunchtime, and wapit before I go to sleep.

The book is full of references to defunct companies, and reader can easily skip the chapters if some companies sound more interesting than others. The chapter names are well-chosen and represent the author's style well. "$100 SHOPPING SPREE IF YOU READ THIS CHAPTER" talks about the numerous get-paid-for-browsing-the-Internet companies, the industry that was pioneered by AllAdvantage.com and supported later by numerous copycats. "Portals to nowhere" talks about such huge money-burners as Go.com and QuePasa.com. The chapter for 'miscellaneous' companies that did not fit any other chapter is titled "I've no fucking clue."

If you look for objective analysis, or used to work for some of the companies mentioned in the book, do not buy it if you consider yourself a sensitive person. Kaplan disparaging remarks are what makes this book a worthy read. Here are some of the selected quotes regarding bankrupt dot-coms.

IHarvest.com: "I don't think I've ever seen a more useless company than iHarvest.com. Actually, I am sure of it. Such a waste."

CalendarCentral.com: "Why would an application service provider like CalendarCentral.com, a site that provides shared, online calendars for group scheduling, go out of business? Microsoft Outlook/Exchange you say? [description of business model that never worked follows] Another one assimilated by the Borg... and Microsoft probably didn't even notice."

OnlineChoice.com: "And this one cost investors around $20 million and employed seventy people. Seventy people. This business, this WEBSITE, could have been run by a SCRIPT. Zero employees. Okay, MAYBE a couple of people to broker deals with suppliers."

SwapIt.com: "So let me get this straight: 1) I send them a CD. 2) They give me useless "SwapIt Bucks." 3) They go out of business. 4) I get nothing. Great, sign me up! [...] I believe this is the only dotcom that actually had people SENDING them product and they STILL couldn't stay in business."

Being a Web developer, Kaplan just goes into fits when talking about the high-cost Web site development. He admits that some sites might be more demanding than others, but any 6- or 7- digit number and above, in his opinion, is just plain ridiculous. Talking about Rx.com, Kaplan is blunt: "This company had $350 million to build a fucking website and market it a little. I mean, if they spent $1 million a year, they could have been around for hundred of years without a single sale." In a two-page rant about high-cost developer MarchFirst.com, Kaplan admits: "Anyway, building websites is relatively easy. That's not to say that everyone can do it, nor that anyone would be interested in learning how. [...] Generally, it's not brain surgery (which I'm assuming is kinda tricky). [...] I'm an idiot and even I was able to build a successful small business building websites. Thing is, we didn't charge millions to build a five-minute CGI email form. That's why we're still around." (Kaplan's agency is PK Interactive.)

By now you should get a feel of the book. It's easy to read, and is sometimes just hilarious, as Philip Kaplan has good-quality sarcasm almost in every sentence. The book would be of interest to tech types, especially those who had been involved in dot-com craze. For serious business types it provides valuable lessons on how not to run a new business. Kaplan's book is a valuable addition to the history of the Internet economy.

Slashback updates tonight on sky-diving cars, Microsoft's new code Glasnost (guess who's signed up to see the code?), the fate of the PCI-SIG list, the SCO and Linux licensing brouhaha, music royalties in Finland, and more. Read on for the details.

Not like that un-American GPL. agentZ writes "The first Microsoft government customer to buy access to the Windows source code is Russia according to this CNet story. Interesting to note FAPSI, one of their intelligence agencies, authorized the purchase. Perhaps they're looking for vulnerabilities in the U.S. Government's dependence on Microsoft?"

The difference between Chapter 11 and The End. prostoalex writes "In regards to a recent heated discussion on whether tech companies can make it out of Chapter 11 bankruptcy protection, XO Communications, the telecom company of the dot-com era, seems to be doing quite well after filing Chapter 11. The article on Internet.com also mentions another company, Covad Communications, picking up customers and more business after filing for Chapter 11."

There's hope in PCI Land. Regarding the Slashdot post of a few days ago about the PCI-SIG ("The End of the Free PCI Device List"), PCI-SIG Chairman Tony Pierce writes

"YourVote.com Supporters:

Thank you for making us aware of your concerns regarding Jim Boemler's online Vendor and Device Lists for the PCI technology.

There has been a misunderstanding between PCI-SIG and Jim - PCI-SIG officers are currently working with Jim to resolve the issues as quickly as possible. We respect Jim Boemler's work and are committed to support the PCI specification efforts industry-wide. We are confident that we will come to an amicable resolution.

We are pleased to see the strong industry support for PCI technologies and value your response to the issues. We understand this site has been a very valuable tool and are working together to find a solution to make sure that the tool is available to the public in some way.

Thank you for your support over the years. We will be sure to keep you informed as we come to resolution in this situation."

This lowers Finland on my list of vacation spots. E-Tray writes "It seems that Finnish equivalents of American RIAA, Teosto, which represents songwriters and publishers, and Gramex, which represents music producers and artists, want to force Finnish day nurseries to pay royalties every time nursery staff sings along with kids. Previously Teosto enforced a law that taxi drivers have to pay royalties if they play music while a customer is in the backseat."

Would still rather see a statement signed in blood. Error27 writes "Earlier this week, Slashdot linked to a Maureen O'Gara article that claimed SCO was probably going to try charge Linux users $96 per CPU. More than one person thought SCO's denial was, "Awfully ambiguous". Hopefully this article clears up any doubts. Essentially, SCO will continue to charge IBM but not RedHat or SCO's UnitedLinux partners."

Perhaps I can volunteer my dad's Suburbans? Finally, joe jennings writes

"A few months ago you ran a story about the cars my team and I skydived with and crashed into the desert. This is a bit of an update.

Next month, we're going to blow up my Nissan Pathfinder. Its twisted remains will be welded to a steel beam and planted on a plot of land in the mojave desert. We're starting "suv ranch," a tribute to gas guzzlers, a dying trend (we hope).

I intend to thoroughly document the project and will post images and quicktime videos on gaspig.com."

prostoalex writes "Online Journalism Review posted an interview with Matt Groening, the mastermind behind The Simpsons and Futurama. Matt lists his favorite comic sites, talks about how Internet changed the cartoons, shares his view on Fox Network's idea to put Simpsons on cell phones, as well as his own plans for Web cartoons."

prostoalex writes "Discover magazine provides an interesting insight into the future technologies that will emulate the human brain. While artificial intelligence supporters always considered direct emulation of brain functions too complex and preferred the top-down approach, some people are researching the ways human brain processes data. One of the interesting discoveries, mentioned in the article, is ability of the brain to re-architect the links as new information is added."

prostoalex writes "The consortium of three universities and four Japanese companies is investing $25M into a project, that is supposed to deliver a 1.5 TB (that's a terabyte and a half) Digital Versatile Disk by 2010. The Inquirer story quotes multiple layers being used for storage." More importantly, they claim that this will be backwards compatible to existing DVD technology.

prostoalex writes "America's Network magazine, the publication serving to telecom industry, takes a look at the disruptive technologies over the next five years. Disruptive, naturally, for telecom industry. Virtual keyboards, DWDM, broadband connections using powerlines, wearable computers, free-space optics, low-power devices, UltraWideBand, voice over 802.11b and numerous others are discussed, as well as their potential for development over the next five years."

prostoalex writes "Gillette announced its intent to purchase 500,000,000 RFID tags from startup Alien Technology. The company expects to introduce RFID tags into its pallets and cases, according to the article. Alien Technology was the first company to introduce an RFID tag with price lower than 10 cents, even though some people claimed it could not be done."

prostoalex writes "Fortune magazine runs an article on New York - based FreshDirect, provider of high-quality groceries. Unlike Webvan, which failed with $1B of venture capital, FreshDirect seems to make pretty good money off online grocery sales - revenues of $225M are projected by 2004. The minimum order is set at $40, the company also charges $4 for delivery." If you want to check out their store, try zip code 10022.

prostoalex writes "National Semiconductor and ARM Holdings will jointly develop the power management solution for RISC chips, that they estimate will improve battery life by 25-400%. The target date of the first sample product is Q2 2003." My old Tadpole laptop sure could have used this. I counted myself as lucky when I got a whole 45 minutes out of a battery.

prostoalex writes "Sony Ericsson announced their new PCMCIA GPRS wireless modem, capable of delivering 57.6 Kbps. It is tri-band and works in 900/1800/1900 MHz range, which led Sony Ericsson to imply that the card will work in 160 countries, providing an always-on Internet connection. Currently only Microsoft operating systems (starting at Windows 98) are supported. No exact price information on official site, but the PC Pro article above quotes 200 UK pounds. The manufacturer also runs a contest for those who would rather get one for free."

prostoalex writes "Arthur Lavine was working for Chase Manhattan bank as a principal photographer. Computer Museum runs an exhibit of Arthur Lavine's photographs of old computer and data processing equipment. Fifteen black-and-white photos from the era where computers were still heading for 1.5 ton benchmark."

prostoalex writes "In an effort to boost the economy state of Idaho legislated tax credit for companies, who were investing in broadband Internet infrastructure. According to the latest news, the plan worked quite well, and about 150 thousand people can soon take advantage of tax-sponsored buildout. Speaking of wiring rural areas with cheap Internet access, there was an article in NY Times ($free_registration_quote), where Bill Gates admitted that in many cases building Internet in the rural area just speeded up the exodus of farmers, who were able to find a job somewhere else."

prostoalex writes "After MIT's decision to put the course materials online free of charge, seven other universities expressed similar goals. With the grant from Hewlett-Packard the universities of Washington, Rochester, Toronto, Cornell, Columbia, Ohio State as well as MIT will provide their courses online at a single location. DSpace was launched with a $1.8 million grant from HP. MIT expects to spend about $250,000 annually to maintain and operate the archive. The page is available here." We also have an update on MITs courseware offerings, so read more if you care about such things. In related news, dchud writes "DSpace, which has been in production use at MIT Libraries since September, is now available under a BSD-style license as version 1.0 at sourceforge. DSpace is a repository for capturing, persisting, and providing access to the digital research output of the MIT community, and will be the long-term archive for OpenCourseWare materials. Now it's available as an institutional repository platform for the rest of the world. See also coverage from the Boston Globe, CNET, and the AP (via NYT, reg req'd)."

prostoalex writes "It looks like Sirius Satellite Radio is going through its worse times. From the same article XM Satellite does not seem to be doing well either, even with 200K customers. Will it signify the end of the satellite radio?"

prostoalex writes "For a while academia and R&D labs explored the possibilities of asynchronous logic. Now Bernard Cole from Embedded.com tells us that asynchronous logic might receive more acceptance than expected in modern designs. The main advantages, as article states, are 'reduced power consumption, reduced current peaks, and reduced electromagnetic emission', to quote a prominent researcher from Philips Semiconductors. Earlier Bernard Cole wrote a column on self-timed asynchronous logic."

prostoalex writes ""Almost everything you think you know about spectrum is wrong." - starts Kevin Werbach in his working paper Open Spectrum: The New Wireless Paradigm. He touches the possibilities of using open spectrum, and then dwells on such innovative products like software-defined radios, spread spectrum or cooperative wireless networking. Truly informative insight into where the U.S. government stands on the issues of wireless spectrum, where it should be, and how it will benefit society and individuals."

prostoalex writes "According to an MSNBC story, 104 million telemarketing calls are made daily in the U.S. alone and technology is on the way to fight those special offers and incredible credit card rates. Zenith EZ HangUp, The Phone Butler, TriVOX VN100 and ScreenMachine are quoted in the article as new gadgets that allow phone owners to avoid the plagues of telemarketing."

prostoalex writes "The definitive study on bellybutton lint, a dog-to-person translation device and an inquiry into what arouses ostriches were recognized at 2002 Ig Nobel awards. The telecast of the event in RealMedia format is available from Harvard University server, there's also an Associated Press story. Ig Nobel awards typically recognize the most dubious contributions to the world of science and research."

prostoalex writes "BusinessWeek questions the validity of security certifications in the modern world. They take a look at Federal Information Processing Standard and the certification process. Apparently 'the testing companies make money by certifying products, not catching problems' thus implying that the seal of approval might not mean a whole lot."

prostoalex writes "Remember Bon Jovi trying to fight piracy with individual PIN numbers that legitimate buyers could get off the CD? DownloadCard, who claims to have invented the technology, filed a lawsuit against Universal Music Group saying the music execs stole the technology and trade secrets from the company. Yahoo! Launch headline suggests that Bon Jovi album might be delayed because of the lawsuit."

prostoalex writes "Dow Jones News asked several mahor scientists and technologists about their worst and best predictions of the future. The story, republished at Yahoo! Finance Singapore quotes Lester Thurow, Professor of management and economics, Massachusetts Institute of Technology's Sloan School of Management; Nicholas Negroponte, Founder and director, Massachusetts Institute of Technology Media Lab; Glover Ferguson, Chief scientist, Accenture; Alan Nugent, Chief technology officer, Novell; Peter Cochrane, Director, ConceptLabs; Michael Earl, Dean, Templeton College, University of Oxford. There seems to be a common agreement on having overrated the ability of machines to talk back to users and vice versa."

prostoalex writes "The DRU500A by Sony burns DVD-R/-RW, DVD+RW/+R, and even CD-R/CD-RW discs. The price sticker is relatively high, but for those worried about the compatibility issues of DVD burners this one looks like a solution." FYI: I recently ran a poll on this very topic.

prostoalex writes "With more companies developing the chips for DVD players the price wars might ensue. According to this DigiTimes report, 'Boosted by rising shipments, the higher price of DVD player single-chips is likely to push up the average chip price to US$9.56 in the fourth quarter from US$8.58 in the first half. However, the increasing number of chip suppliers also implies that a new price war may soon develop'. The predictions of DVD chips sales slowing down add to the expectations for price wars."

prostoalex writes "Ultra WideBand radio is a technology that allows transmitting huge amounts of data over a short distance at very low power. At Intel Developer Forum this week Ben Manny, director of wireless technology development at Intel Research and Development, promised market deployment of UWB-based solutions by 2005-2006. Possible applications of UWB can be discovered in this article that also refers to UWB as 'Bluetooth on steroids'."

prostoalex writes "On Intel Developer Forum ViewSonic introduced its 200 dpi display. The 22.2 inch 3840x2400 monitor will sell for around $8,000." Maybe there's hope for all those obsessive folks trying to run Quake 3 at insane resolutions. Provided they'd rather have a monitor than eight grand!

Blog, Blog, Blog. Recent media infatuation with the blogging effect seems to be overwhelming. It seems that newspaper journalists have just discovered the ability to post and comment messages on the Internet, while most of the computer aficionados and heavy Internet users just shrug their shoulders when told about personal Web journals that link to other articles on the Web.

Blogging Essentials is mostly a generic guide to setting up and running your own Weblog using the software available out there. It doesn't require as much technical knowledge and Unix experience as Running Weblogs with Slash, and doesn't have a nice preface by CmdrTaco, but for a person who is determined to keep a daily journal available on the Internet, it would provide helpful reading material.

What's reviewed

Blogger, Radio Userland and MovableType are the primary products discussed in the book. Each of these packages has two chapters dedicated to it, one for beginners' introduction and one for description of advanced features. The main difference between these three products is in their hosting capabilities - Blogger wants you to keep the journal entries on its Web site and provides Web interface, Radio UserLand keeps the posts on its own server as well, while providing desktop interface, while MovableType assumes the user has a Web server on which to install the blogging software. Both Blogger and Radio UserLand allow for self-hosting, which is also covered in introductory chapters.

Another chapter is dedicated to server-based Blosxom, and in the review of desktop clients such blog utilities as BlogScript, BlogApp, BlogBuddy, W.Bloggar and Slug are covered.

What's good and what's bad

While the depth of covered material is surprisingly large for such a narrow topic, a lot of book pages are spent on displaying screenshots of the blogging software, and showing other people's blogs. The only thought that never left my mind while reading this book was "Who would buy it?" Why would you need 264 pages to explain you how to set up your own journal and run it? People who find satisfaction in running their own customized versions of online journals already know most of the material, and those who don't would probably opt in for easier Web-based interface like LiveJournal.

The book seems to be just a quick walk-through of the manuals, and if you consider that all of the reviewed products have pretty good help and FAQ sections, the need for such book decreases even more. I can hardly name anyone to whom I would recommend this book.

prostoalex writes "With the demise of free Internet access providers, it's interesting to see this model working in Egypt, where the state-owned telecom allows people to dial-up for free as long as they pay the regular phone access fees. Associated Press quotes the phone line charges being 25 cents per hour. The ISPs that promote free Internet access from Telecom Egypt are then given their share of the profit."

prostoalex writes "A recent issue of Berkeley Lab Research Review discusses the nanosecrets of everyday things. The article talks about common everyday applications of nanotechnology advances, as well as takes a look at tools used to manipulate itty-bitty widgets."

Alexander Moskalyuk writes "Most of the people I know have a love-hate relationship with Kip Irvine's Assembly Language for Intel-based Computers. Ask any student who used this textbook and you will either get a cheerful 'I've used it, it's great, I learned Assembly, and it has lots of useful examples' or resentful 'The book is horrible, hard to follow and full of code that is irrelevant to the contents of a specific chapter.'" Alexander's review of the book (below) concentrates on its role as an instructional aid, and on the differences between the third and fourth editions. Assembly Language for Intel-Based Computers, 4th edition author Kip R. Irvine pages 676 publisher Prentice Hall rating 8/10 reviewer Alexander Moskalyuk ISBN 0130910139 summary Authoritative source on Intel assembly programming and Assembly language fundamentals

Popularity Contest of One A quick search on Amazon, however, reveals that for the keyword 'Assembly' Irvine's book is still the bestseller. The fourth edition of the text tops the list and the same was the case with the third edition. The university where I teach uses Irvine's textbook for its introductory Assembly courses. We've used third edition throughout last year, and decided to stick to the third edition (with fourth recommended) during this academic year as well, just to avoid having students cash out for a newer version of the same text. Since this is a Prentice Hall textbook targeted mostly towards Computer Science and Engineering programs, welcome to the world of academic pricing -- the list price of fourth edition is $76.

Third vs. Fourth

The first natural thing to do is to see whether the fourth edition of the text is superior to 1999's third edition. Just looking at the table of contents, you can see that a lot of new material has been added, even in the introductory chapters. Furthermore, fourth edition has a new version of the first Assembly program introduced to the reader. Instead of the notorious 'Hello, World' example, it's now adding three numbers. Hello, World would usually be the thing to introduce first in classes with C++ or Perl being primary languages. However, in Intel Assembly the example just confused students more, since printing the phrase "Hello, World" to the screen involved dealing with interrupts, and that topic would not be covered until later in the course.

Irvine also got rid of his "Using the Assembler" chapter, which might be a nuisance for some of the readers and relief for others. The book comes with Microsoft ASM and thus all examples assume using MASM for their compilation needs. In my class, however, NASM has always been the compiler of choice, partly because it's easier to introduce to novice programmers who have not been exposed to Assembly before, and partly because of the tradition -- NASM was the compiler that previous instructors used, and thus was available on university servers and familiar to tutors in the labs. Vaguely named "Advanced Topics" chapters are almost gone and now changed into much more informative "16-bit MS-DOS programming," "Expert MS-DOS programming," "BIOS level programming," "32-bit Windows programming" and "High-level language interface." The last chapter of the book is now the only one bearing the name "Advanced Topics" and discusses things like "Hardware control with I/O ports," "Intel instruction encoding" and "Floating-Point arithmetic."

Some appendices are gone as well. The third edition included such topics as "Binary and Hexadecimal tutorial" (now moved to be a part of the introductory chapters), "Using debug" (tutorial on using debug.exe on Microsoft platforms to trace the Assembly code -- it's a shame the appendix is pulled out of the book, since now either students have to learn the commands for debug.exe themselves or additional class time needs to be spent on that), "Microsoft CodeView" and "Borland TurboDebugger" (both gone for good) as well as "Guide to the sample programs" (in this new edition, that successfully migrated into "Installing and using the assembler").

Except for the shocking absence of debug.exe tutorial appendices, the fourth edition looks much more straightforward and useful. Speaking of appendices, there are four of them now - "Installing and using the assembler," which few people ever bother to read when in class, "Intel instruction set," which is the mother of all useful appendices (in fact, I've seen good students get by on nothing else but this appendix), "BIOS and MS-DOS interrupts" and "MASM reference." The CD by the way, includes MASM, source code and macros for the book, as well as evaluation version of TextPad.

Academic value

Kip Irvine is usually accused of bringing up examples that confuse novice readers and trying to show off with his knowledge of IA-32 Assembly. Read the Amazon reviews to find out more. Personally I have never had problems with his style of writing. There were, though, some mistakes in the third edition of the book that would make an instructor pull his hair to pieces. Typos, grammatical errors and words that did not get picked up by the spellchecker were acceptable, but when the sequence of operations during code execution was described incorrectly, you can hardly be accused of being too picky, since you get students relying on the book for knowledge and being mad at you for flagging their code wrong on the test.

If you have the third edition handy, pages 234 and 235 describe the RCL and RCR operations, providing the incorrect order of operations and thus forcing students who use this textbook to learn these instructions to arrive at incorrect results when given a snippet of code to trace. Page 232 in the fourth edition now has the correct sequence of operations.

I would lie to you if I told you that I've read the whole book. Very few people would actually need to go through seven hundred pages, and some of the things discussed might never be useful even if you spent the rest of your life programming Intel Assembly 40 hours a week. But from the information that I got after reading the chapters that interested me (mostly introductory material and all chapters that cover instruction set and interrupts), the text seemed to present material in a clear and straightforward manner, with abundant examples.

A nice addition to Chapter 1 was an explanation of how virtual machines work, since the university uses Java as its core programming language. The second chapter goes on smoothly with careful introduction into the architecture principles and then switches into overdrive, presenting students with information on "Multi-stage pipelining" followed by reasonably simple material on "How programs run."

The book jumps into IA-32 architecture, although I wish that for introductory class the text would stick to 8086 architecture, and then have the 32-bit registers introduced. But generally it's a thorough and informative text for anyone deciding to learn programming Assembly language on Intel platforms, or just beginning Computer Science majors deciding to find out how the stuff really works as opposed to playing with high-level APIs.

The table of contents can be found at publisher's Web site. There's also a Web page for the book, where the author has posted some chapters in PDF format. The chapters published for free include Chapter 1 - Basic Concepts, Chapter 2 - IA-32 Processor Architecture, Chapter 6 - Conditional Processing, Chapter 11 - 32-bit Windows Programming, Chapter 15 - BIOS-level programming as well as Preface and Table of contents.

This article in eWeek talks about the current problems with fuel cells, and claims that 'these devices, designed to last as much as 10 times longer than a standard lithium-ion battery, should hit the market by 2004.'" There are a few fuel-cell devices on the market, but this article points out a few reasons they're not yet more widespread.
